A blood relation problem gives you a series of family relationships in words and asks you to work out how two specific people are related, often by tracking the relationships through a family tree.
These questions test your ability to track multiple relationship statements simultaneously and correctly determine an indirect connection.
Statement: Pointing to a man, a woman says, "His mother is the only daughter of my mother." How is the woman related to the man?
Solution: "The only daughter of my mother" means the woman herself (since she has no sisters). So "his mother" = the woman. That means the woman is the man's mother.
